The canvas

The canvas is the main work area, located on the Explorer page. To access the canvas, either click Open or on the Home page title bar click Explorer.

Using the canvas, you can:

  • Edit saved flows.
  • Save an existing flow with a new name to create a starting point for a new flow.

Channel
A channel is a connection between two or more stages through which records are passed from one stage to another.
Port
If you look closely at the stage icons you will notice small round port indicators on one or more sides of a stage. A port sends data to stages or reads data from a channel. Stages that read data into the flow ("sources") have output ports since they are at the start of a flow. Stages that send data out of the flow ("sinks") have input ports since they are at the end of a flow. All other stages have both input and output ports.
Some stages have error ports, which output records that cause errors during the stage's processing. Some stages have report ports, which generate reports about the stage's output.
You can hover over a port indicator to view its name.
You can double-click a port indicator to open a page that allows you to configure that port's details. The configuration settings vary depending on the type of operation being defined. Ports show different colors based on their status. The colors, in order of priority are:
  • pink - exception error
  • sky blue - report
  • green - input or output success
  • gray - normal status
